I’ve run into this one a couple of times so far, so I thought it might be good to post the solution :-) In OS X, with Matlab versions R2008b, R2008a, R2007b and R2007a, a Java update on the system may have made the cursor in the text editor not align with the text: you align the cursor with a character, hit delete, and a character several spaces over goes away. VERY annoying. Mathworks has a patch to fix this, available at http://www.mathworks.com/support/bugreports/details.html?rp=495091 (you’ll [snip...]
I was working with a grad student this weekend to take advantage of compute resources effectively, and one of the questions that came up was how run Matlab non-interactively as well as persistently.
To run Matlab persistently (so it doesn’t die when you log out), “screen” can be used as described at this link.
To run Matlab non-interactively, I found a concise and useful page with instructions and explanations: http://people.scs.fsu.edu/~burkardt/m_src/matlab_batch/matlab_batch.html .
Most, if not all, of the Thayer-based readers of this blog will have used one of the print release stations spread through our building. Each release station requires a computer to run the release software on. The computers at the release stations are not new, but still quite beefy (and power hungry at ~70 watts) for the job they have to do.
Enter the DecTOP. The DecTOP is relatively old technology, designed by AMD years ago, with a 366 MHz AMD [snip...]

When I left you in my last post on saving energy in the computer labs, I had four machines suspending in the M210 computer lab. There were mixed results during the test run. The older, Dell Dimension 4600 computers went to sleep and woke back up without a problem, however the newer Dell Optiplex 745 computers failed to come out of suspend approximately 30% of the time. Try as I might, updating drivers and playing with BIOS and power settings, I was unable to [snip...]
Ever wonder how much power an average idle computer takes to run? A newer Dell Optiplex 745 with a 22″ LCD monitor, such as those in M210, consume 110 Watts just sitting there, not logged in with the screen saver on. When the monitor goes into power save mode, the consumption goes down to 70 Watts. When the computer itself goes into standby mode, power consumption plummets to just 2 Watts. Since most of the ~65 Thayer lab computers are idle most of the time, [snip...]
